Aliphatic polyurethane varnish
Equal polyurethane lacquer is a two-component varnish of acrylic and isocyanate. How it hardens is the result of solvent evaporation and molecular polymerization resulting from the reaction of two components.

Description of solvent-free sanitary epoxy primer
Its properties include:
- Very good corrosion resistance
- High chemical resistance
- High abrasion resistance and hardness
- Excellent water and moisture resistance
- Good adhesion to steel surfaces
- Applicable with thicknesses over 200 microns
- Surface impermeability
- Designed for health systems
- Shine and excellent appearance
Uses
This coating is used alone as the final layer of sanitary epoxy systems and drinking water to protect the surfaces against corrosion and microbes. Due to the high solid percentage of paint with a spraying step, thicknesses up to 500 microns can be achieved. Its uses include:
- Drinking water tanks
- Water transfer pipes
- Sanitary equipment
- Industrial Drug Making Machines
- Food Equipment
- Food storage cells
- Sanitary ware containers
- Clean hall and operating room flooring

Surface preparation
Painted surfaces – These surfaces must be completely clean and free of any grease and other contaminants. Before painting, the surface should be completely dry and if a long time has passed since the application of the undercoat, a suitable roughness should be created by soft sanding on the surface.
Steel surfaces – Wash the steel surface with a suitable solvent to remove grease, salt and any other contaminants.
De-rust and create profiles on surfaces by various methods such as sand blasting up to 2.5 degrees Swedish or by mechanical tools up to ISO-ST3 degree.
In metal structures and welded points and corners should be smooth and polished and free of any appendages and sharpness. After de-rusting and creating a profile, remove the particles from the preparation and other contaminants from the surface with a pressure of air free of moisture and grease and with the method of vacuum and thoroughly clean.
Note that the application of the first layer (primer) should be done no later than two hours after preparation.
Concrete surfaces – If the concrete is fresh, it must be 28 days after the concrete has been applied (the concrete surface is completely dry). If the concrete is old, the surface must be washed with fresh water to remove contaminants such as salts, grease, dust and Dust, loose and unstable particles, etc. from its surface
